To aZZ whom it may concern,.-

Be it known that l, FREEMAN N. COTTLE,

Massachusetts, haveinvented an Improvement in Tripods, of which. thefollowing'description,

ings is a specification, like letters on the draw- This invention hasfor its obj ect to construct a tripod .to be used, amongother purposes,for

v The invention consists in a tripod'composed of three independentsupporting-legs combjned with a shell or case to which the said legs orsupports are `pivotally connected, and a therewith, the said devicebeing herein shown y.their connection with the shell or case. The lmeanshereiny shown for moving the guide` plate is a plug provided withsockets to receive arms to support any article to be exhibited, the saidplug being free to be rotated Y Figure 1 shows in front. elevationa-tripod embodying this invention, the legs and tablet or chart supportsbeing broken out to save tion of the shellfor case Whichreceives theupper ends of the legsand the retaining or locking device for the legs;Fig-3, a side elevation ing device being withdrawn to. permit the legsing-plate for the locking device, and Fig. 5 a modification to bereferred to. Y

The threelegs a b' c, of any suitable length legs are spread the portion2 will occupy substantially a vertical. position; Thet extreme upperends of the supports are also bent outwardly at substantially rightangles, as at 3. The shell or lcase d is'provided with perfora-,`

tions through its side walls,which receive the Y outwardly-bentportionsf3 'of' the; legs or vsupl ports. y Aj locking or retainingdeviceisprovided to hold the'supp'orts iirmlywhen spread,f

as when thetripod is in position for'use, as in Figs. 1 and 2, and alsowhich may be lifted or 6 0 The 'guide-plate le has erected uponit astud, 7o

e2, which receives on it loosely a cylindervor plug, f, which yis madesmaller in diameter than .the shell or case d, to receive between itland the shell or case d the vertical'portionof the supports.-`Thecylinder orplug fispro-.75 vided at its upper end with aiange, f,which co-operateswith a ilange,l f2, of theV shell or-r case to limitthedescent of'the cylinder'or lug. ,V,. l- Y. The cylinder or plug fhas atits topy suit- 8o able sockets, as 5, `which may be either straight orinclined to receive suitable brackets,fsup

ports, or arms, as g, to sustain al map, chart, or other thing orarticle to befexhibited, the upper ends of the saidarms g being bentAout-` Wardly, as at 7, and provided preferablywith' notches, as 8, tolaid in holding in place `suitable clips, as p, made, preferably, fromwire. [twill be seen that Awhen lthe cylinder or plugf is elevated orpartially Withdrawn, as 9o shown in Fig.' 3, suiicient space isleftwithin theshell or case to permit the supports ab c to be broughttogether parallel with each other, and by pressingthe saidcylinde'r or iplug f into kthe shell' or case, as shown in Fig. 95 2, the saidleg's orsupports are spread and so. i heldrmly. i

If desired, in addition to: the guide-plate.,e,

which is employed to spreadthe supportsI i may employ a secondVguide-plate, as ,(seeroo Fig. 5,) which hasradial slots, as 9, to .per-

the arms and plug f, may be rotated as and when desired, to .exhibit thething supported by the arms to an audience in any direction.

I claim-1 l. In a tripod, the legs or supports a b c and the shell orcase d, combined with the locking or retaining device sliding Within thesaid shell, substantially as described, for holding the supports spreadand permitting them to lie parallel as desired,and with arms or bracketserected in the said locking device, substantially as and for thepurposes set forth.

2. In a tripod, the legs or supports a b c, bent outwardly at theirupper ends, as at 2, combined with the shell or case d, havingperforations in its cylindrical portion, as shown, and the locking orretaining device movable in the said shell, and provided with arm orbracket receiving sockets 5, substantially as the cylinder shell orcase, combined with the locking or retaining device therein for the legsor supports, consisting of the cylinder or plug f, provided at its topwith sockets to receive arms or brackets, and the guide-plate e,looselyconnected thereto, substantially as described.

5. In a tripod, the shell or case, the legs or supports a b c', madedetachable, asshown and described, and the chart-sustaining arms orbrackets g, combined with the locking or retaining device within thesaid shell for and cofoperating with the upper ends of the legs orsupports, substantially as described.

6. In a tripod, the legs, the retaining shell or case d therefor, thesoeketed rotatable sliding plug within the said shell, and arms to enterthe said socketed plug, substantially as described.

7. In a tripod, the shell or case d, the rotatable sliding plug therein,the legs intermediate the said shell and plug, and supports or arms g,erected in the said plug, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
